13 Really Useful Online CSS Tools to Streamline Development CSS is nearly used on every modern website design. However, having to write and structure CSS code from scratch every time you have a project is extremely time consuming. Below, we present you with 13 amazingly useful CSS tools for hacking on writing time consuming code. We tried to place emphasis on unknown tools that every developer should have a looksy at, however don’t be surprised if we included a few known sources. CSS Cheat Sheets As simple tool as this may seem, the CSS Cheat Sheet can be very useful. Telerik Visual Style Builder Telerik Visual Style Builder is an online CSS customization tool that allows you to easily, point-and-click customization of skins for the RadControls for ASP.NET AJAX. This tool is ideal for ASP.NET developers. CSS Type Set CSS Type Set, a hands-on typography tool which allows the every day designer and developer fully test and learn how to style Web content.

How to write and read a color in C# Transforming a color in hexa representation using following function: private string WriteHexString(byte aobjColR, byte aobjColG, byte aobjColB){string strRet;byte[] btR = {aobjColR};string strR = ToHexString(btR);strRet = strR; byte[] btG = {this.colorDialog1.Color.G};string strG = ToHexString(btG);strRet += strG; byte[] btB = {this.colorDialog1.Color.B};string strB = ToHexString(btB);strRet += strB; return strRet;}//WriteHexString This function transform a Color (defined as Color.R, Color.G, Color.B) in hexa representation (as string) and use following helper functions: private static string ToHexString(byte[] bytes) {char[] chars = new char[bytes.Length * 2];for (int i = 0; i < bytes.Length; i++) {int b = bytes[i];chars[i * 2] = hexDigits[b >> 4];chars[i * 2 + 1] = hexDigits[b & 0xF];}return new string(chars);}//ToHexString static char[] hexDigits = {'0', '1', '2', '3', '4', '5', '6', '7','8', '9', 'A', 'B', 'C', 'D', 'E', 'F'}; and helper function: The complete code is in zip file.

Welcome to Linux From Scratch! PxLoader | A Simple JavasScript Preloader A JavaScript Preloader for HTML5 Apps PxLoader is a Javascript library that helps you download images, sound files or anything else you need before you take a specific action on your site (like showing a user interface or starting a game). You can use it to create a preloader for HTML5 games and websites. It let's you monitor download status by providing progress and completed events and it lets you prioritize the order in which items are downloaded. You can even tag groups of files and then prioritize downloads or register for events by tag. We created PxLoader for the HTML5 version of Cut the Rope and out of the box works great with images and sound files (the types of resources we needed for the game), but it's designed to be extensible and work with any file type or other network action. Step by Step Instructions 1. *The sound file downloader works with SoundManager 2 and allows it do the heavy lifting of the actual download. 2. 3. Download Images Before Drawing to a Canvas add(resource)

VisuAlgo - Sorting (Bubble, Selection, Insertion, Merge, Quick, Counting, Radix) VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace. VisuAlgo contains many advanced algorithms that are discussed in Dr Steven Halim's book ('Competitive Programming', co-authored with his brother Dr Felix Halim) and beyond. Today, some of these advanced algorithms visualization/animation can only be found in VisuAlgo. Though specifically designed for NUS students taking various data structure and algorithm classes (e.g. CS1010, CS1020, CS2010, CS2020, CS3230, and CS3233), as advocators of online learning, we hope that curious minds around the world will find these visualisations useful too. VisuAlgo is not designed to work well on small touch screens (e.g. smartphones) from the outset due to the need to cater for many complex algorithm visualizations that require lots of pixels and click-and-drag gestures for interaction.

Python Programming Methodology - Download free content from Stanford Binary search algorithm In computer science, a binary search or half-interval search algorithm finds the position of a specified input value (the search "key") within an array sorted by key value.[1][2] For binary search, the array should be arranged in ascending or descending order. In each step, the algorithm compares the search key value with the key value of the middle element of the array. If the keys match, then a matching element has been found and its index, or position, is returned. Otherwise, if the search key is less than the middle element's key, then the algorithm repeats its action on the sub-array to the left of the middle element or, if the search key is greater, on the sub-array to the right. A binary search halves the number of items to check with each iteration, so locating an item (or determining its absence) takes logarithmic time. Overview[edit] Searching a sorted collection is a common task. Examples[edit] Example: The list to be searched: L = 1 3 4 6 8 9 11. Compare X to 6. .

Arch Linux Humor - How to Shoot Yourself In the Foot Using Any Programming Language The proliferation of modern programming languages (all of which seem to have stolen countless features from one another) sometimes makes it difficult to remember what language you're currently using. This guide is offered as a public service to help programmers who find themselves in such dilemmas. 370 JCL You send your foot down to MIS with a 4000-page document explaining how you want it to be shot. Three years later, your foot comes back deep-fried. Ada After correctly packaging your foot, you attempt to concurrently load the gun, pull the trigger, scream, and shoot yourself in the foot. When you try, however, you discover that your foot is of the wrong type. APL You shoot yourself in the foot, then spend all day figuring out how to do it in fewer characters. ASP.NET Find a gun, it falls apart. Assembly You try to shoot yourself in the foot only to discover you must first reinvent the gun, the bullet, and your foot. BASIC Shoot yourself in the foot with a water pistol.

The Selection Sort The selection sort improves on the bubble sort by making only one exchange for every pass through the list. In order to do this, a selection sort looks for the largest value as it makes a pass and, after completing the pass, places it in the proper location. As with a bubble sort, after the first pass, the largest item is in the correct place. Figure 3 shows the entire sorting process. Figure 3: selectionSort Selection Sort (lst_selectionsortcode) You may see that the selection sort makes the same number of comparisons as the bubble sort and is therefore also . Self Check Q-22: Suppose you have the following list of numbers to sort: [11, 7, 12, 14, 19, 1, 6, 18, 8, 20] which list represents the partially sorted list after three complete passes of selection sort?
